Well to be fair, Windows is MS property and for better, or worse, they can do as they please with it. In all fairness, the way I see it, since Windows is MS property, they really should be the ones shouldering the burden of keeping it safe. Others have profited by doing this for MS, due to their stupidity over the years. Thing is, for MS to properly lock things down, it will block what 3rd parties can do, or have access to. 3rd parties also do create problems, so it really isn't only MS as some claim. What about issues with HTTPS and browsers, slow web page laoading, FP of critical system files, causing issues with games and such? These aren't issues that MS created, these are issues that 3rd parties created due to the way they hook into things, etc...
Well of course they will say/think that. Let's cut the BS, these companies are making money on this, so let's be realistic here. If anything cuts into their margins, including MS and WD/ATP, of course they wont be happy. They may have some truth to the matter, but at the end of the day it's still a business for them.
